<!--[![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)](https://pkg.go.dev/github.com/lbryio/lbcd)-->
btcd is an alternative full node bitcoin implementation written in Go (golang).
`lbcd` is a full node implementation of LBRY's blockchain written in Go (golang).
This project is currently under active development and is in a Beta state. It
is extremely stable and has been in production use since October 2013.
This project is currently under active development and is in a Beta state while
we ensure it matches LBRYcrd's functionality. The intention is that it properly
downloads, validates, and serves the block chain using the exact rules
(including consensus bugs) for block acceptance as LBRYcrd.
We have taken great care to avoid lbcd causing a fork to the blockchain.
It properly downloads, validates, and serves the block chain using the exact
rules (including consensus bugs) for block acceptance as Bitcoin Core. We have
taken great care to avoid btcd causing a fork to the block chain. It includes a
full block validation testing framework which contains all of the 'official'
block acceptance tests (and some additional ones) that is run on every pull
request to help ensure it properly follows consensus. Also, it passes all of
the JSON test data in the Bitcoin Core code.
Note: `lbcd` does *NOT* include wallet functionality. That functionality is provided by the
[lbcwallet](https://github.com/lbryio/lbcwallet) and the [LBRY SDK](https://github.com/lbryio/lbry-sdk).
It also properly relays newly mined blocks, maintains a transaction pool, and
relays individual transactions that have not yet made it into a block. It
ensures all individual transactions admitted to the pool follow the rules
required by the block chain and also includes more strict checks which filter
transactions based on miner requirements ("standard" transactions).
## Security
One key difference between btcd and Bitcoin Core is that btcd does *NOT* include
wallet functionality and this was a very intentional design decision. See the
blog entry [here](https://web.archive.org/web/20171125143919/https://blog.conformal.com/btcd-not-your-moms-bitcoin-daemon)
for more details. This means you can't actually make or receive payments
directly with btcd. That functionality is provided by the
[btcwallet](https://github.com/btcsuite/btcwallet) and
[Paymetheus](https://github.com/btcsuite/Paymetheus) (Windows-only) projects
which are both under active development.
We take security seriously. Please contact [security](mailto:security@lbry.com) regarding any security issues.
Our PGP key is [here](https://lbry.com/faq/pgp-key) if you need it.
We maintain a mailing list for notifications of upgrades, security issues,
and soft/hard forks. To join, visit [fork list](https://lbry.com/forklist)
## Requirements
[Go](http://golang.org) 1.16 or newer.
All common operating systems are supported. lbcd requires at least 8GB of RAM
and at least 100GB of disk storage. Both RAM and disk requirements increase slowly over time.
Using a fast NVMe disk is recommended.
`lbcd` is not immune to data loss. It expects a clean shutdown via SIGINT or
SIGTERM. SIGKILL, immediate VM kills, and sudden power loss can cause data
corruption, thus requiring chain resynchronization for recovery.
For compilation, [Go](http://golang.org) 1.16 or newer is required.
## Installation
https://github.com/btcsuite/btcd/releases
Acquire binary files from [releases](https://github.com/lbryio/lbcd/releases)
#### Linux/BSD/MacOSX/POSIX - Build from Source
### To build from Source on Linux/BSD/MacOSX/POSIX
- Install Go according to the installation instructions here:
http://golang.org/doc/install
Install Go according to its [installation instructions](http://golang.org/doc/install).
- Ensure Go was installed properly and is a supported version:
``` sh
git clone https://github.com/lbryio/lbcd
cd lbcd
```bash
$ go version
$ go env GOROOT GOPATH
# Build lbcd
go build .
# Build lbcctl
go build ./cmd/lbcctl
```
NOTE: The `GOROOT` and `GOPATH` above must not be the same path. It is
recommended that `GOPATH` is set to a directory in your home directory such as
`~/goprojects` to avoid write permission issues. It is also recommended to add
`$GOPATH/bin` to your `PATH` at this point.
Both [GoLand](https://www.jetbrains.com/go/)
and [VS Code](https://code.visualstudio.com/docs/languages/go) IDEs are supported.
- Run the following commands to obtain btcd, all dependencies, and install it:
## Usage
```bash
$ cd $GOPATH/src/github.com/btcsuite/btcd
$ GO111MODULE=on go install -v . ./cmd/...
By default, data and logs are stored in `<LBCDDIR>`:
- Linux: `~/.lbcd/`
- MacOS: `/Users/<username>/Library/Application Support/Lbcd/`
To enable RPC access a username and password is required. Example:
``` sh
./lbcd --rpcuser=rpcuser --rpcpass=rpcpass
```
- btcd (and utilities) will now be installed in ```$GOPATH/bin```. If you did
not already add the bin directory to your system path during Go installation,
we recommend you do so now.
Interact with lbcd via RPC using `lbcctl`
## Updating
#### Linux/BSD/MacOSX/POSIX - Build from Source
- Run the following commands to update btcd, all dependencies, and install it:
```bash
$ cd $GOPATH/src/github.com/btcsuite/btcd
$ git pull
$ GO111MODULE=on go install -v . ./cmd/...
``` sh
./lbcctl --rpcuser=rpcuser --rpcpass=rpcpass getblockcount
./lbcctl --rpcuser=rpcuser --rpcpass=rpcpass getblocktemplate
```
## Getting Started
By default, the RPCs are served over TLS. `lbcd` generates (if not exists) `rpc.cert` and
`rpc.key` under `<LBCDDIR>` where `lbcctl` would search and use them.
btcd has several configuration options available to tweak how it runs, but all
of the basic operations described in the intro section work with zero
configuration.
The RPCs can also be served without TLS *(on localhost only)* using (`--notls`)
#### Linux/BSD/POSIX/Source
```bash
$ ./btcd
``` sh
./lbcd --rpcuser=rpcuser --rpcpass=rpcpass --notls
./lbcctl --rpcuser=rpcuser --rpcpass=rpcpass --notls getblockcount
```
## IRC
## Working with Different Networks
- irc.libera.chat
- channel #btcd
- [webchat](https://web.libera.chat/gamja/?channels=btcd)
By default, `lbcd` and `lbcctl` use the following ports for different networks respectively:
## Issue Tracker
| Network | RPC Port | Network Port |
| ------- | -------- | ------------ |
| mainnet | 9245 | 9246 |
| testnet | 19245 | 19246 |
| regtest | 29245 | 29246 |
The [integrated github issue tracker](https://github.com/btcsuite/btcd/issues)
is used for this project.
Running `lbcd` and `lbcctl` with `--testnet` or `--regtest` would use different chain params as well as default RPC and Network ports.
## Documentation
``` sh
./lbcd --rpcuser=rpcuser --rpcpass=rpcpass --regtest
./lbcctl --rpcuser=rpcuser --rpcpass=rpcpass --regtest getblockcount
```
The documentation is a work-in-progress. It is located in the [docs](https://github.com/btcsuite/btcd/tree/master/docs) folder.
The default Network and RPC ports of `lbcd` can be overriden using `--listen` and `--rpclisten`
`lbcctl` can also connect to RPC server specified by `--rpcserver`
## Release Verification
``` sh
./lbcd --rpcuser=rpcuser --rpcpass=rpcpass --regtest --listen=127.0.0.1:29248 --rpclisten=127.0.0.1:29247
./lbcctl --rpcuser=rpcuser --rpcpass=rpcpass --regtest --rpcserver=127.0.0.1:29247 getblockcount
```
Note: Wallet related RPCs are provided by [lbcwallet](https://github.com/lbryio/lbcwallet).

# Code contribution guidelines
Developing cryptocurrencies is an exciting endeavor that touches a wide variety
of areas such as wire protocols, peer-to-peer networking, databases,
cryptography, language interpretation (transaction scripts), RPC, and
websockets. They also represent a radical shift to the current fiscal system
and as a result provide an opportunity to help reshape the entire financial
system. There are few projects that offer this level of diversity and impact
all in one code base.
However, as exciting as it is, one must keep in mind that cryptocurrencies
represent real money and introducing bugs and security vulnerabilities can have
far more dire consequences than in typical projects where having a small bug is
minimal by comparison. In the world of cryptocurrencies, even the smallest bug
in the wrong area can cost people a significant amount of money. For this
reason, the btcd suite has a formalized and rigorous development process which
is outlined on this page.
We highly encourage code contributions, however it is imperative that you adhere
to the guidelines established on this page.
## Minimum Recommended Skillset
The following list is a set of core competencies that we recommend you possess
before you really start attempting to contribute code to the project. These are
not hard requirements as we will gladly accept code contributions as long as
they follow the guidelines set forth on this page. That said, if you don't have
the following basic qualifications you will likely find it quite difficult to
contribute.
- A reasonable understanding of bitcoin at a high level (see the
[Required Reading](#ReqReading) section for the original white paper)
- Experience in some type of C-like language
- An understanding of data structures and their performance implications
- Familiarity with unit testing
- Debugging experience
- Ability to understand not only the area you are making a change in, but also
the code your change relies on, and the code which relies on your changed code
Building on top of those core competencies, the recommended skill set largely
depends on the specific areas you are looking to contribute to. For example,
if you wish to contribute to the cryptography code, you should have a good
understanding of the various aspects involved with cryptography such as the
security and performance implications.
## Required Reading
- [Effective Go](http://golang.org/doc/effective_go.html) - The entire btcd
suite follows the guidelines in this document. For your code to be accepted,
it must follow the guidelines therein.
- [Original Satoshi Whitepaper](http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCkQFjAA&url=http%3A%2F%2Fbitcoin.org%2Fbitcoin.pdf&ei=os3VUuH8G4SlsASV74GoAg&usg=AFQjCNEipPLigou_1MfB7DQjXCNdlylrBg&sig2=FaHDuT5z36GMWDEnybDJLg&bvm=bv.59378465,d.b2I) - This is the white paper that started it all. Having a solid
foundation to build on will make the code much more comprehensible.
## Development Practices
Developers are expected to work in their own trees and submit pull requests when
they feel their feature or bug fix is ready for integration into the master
branch.
## Share Early, Share Often
We firmly believe in the share early, share often approach. The basic premise
of the approach is to announce your plans **before** you start work, and once
you have started working, craft your changes into a stream of small and easily
reviewable commits.
This approach has several benefits:
- Announcing your plans to work on a feature **before** you begin work avoids
duplicate work
- It permits discussions which can help you achieve your goals in a way that is
consistent with the existing architecture
- It minimizes the chances of you spending time and energy on a change that
might not fit with the consensus of the community or existing architecture and
potentially be rejected as a result
- Incremental development helps ensure you are on the right track with regards
to the rest of the community
- The quicker your changes are merged to master, the less time you will need to
spend rebasing and otherwise trying to keep up with the main code base
## Testing
One of the major design goals of all core btcd packages is to aim for complete
test coverage. This is financial software so bugs and regressions can cost
people real money. For this reason every effort must be taken to ensure the
code is as accurate and bug-free as possible. Thorough testing is a good way to
help achieve that goal.
Unless a new feature you submit is completely trivial, it will probably be
rejected unless it is also accompanied by adequate test coverage for both
positive and negative conditions. That is to say, the tests must ensure your
code works correctly when it is fed correct data as well as incorrect data
(error paths).
Go provides an excellent test framework that makes writing test code and
checking coverage statistics straight forward. For more information about the
test coverage tools, see the [golang cover blog post](http://blog.golang.org/cover).
A quick summary of test practices follows:
- All new code should be accompanied by tests that ensure the code behaves
correctly when given expected values, and, perhaps even more importantly, that
it handles errors gracefully
- When you fix a bug, it should be accompanied by tests which exercise the bug
to both prove it has been resolved and to prevent future regressions
## Code Documentation and Commenting
- At a minimum every function must be commented with its intended purpose and
any assumptions that it makes
- Function comments must always begin with the name of the function per
[Effective Go](http://golang.org/doc/effective_go.html)
- Function comments should be complete sentences since they allow a wide
variety of automated presentations such as [go.dev](https://go.dev)
- The general rule of thumb is to look at it as if you were completely
unfamiliar with the code and ask yourself, would this give me enough
information to understand what this function does and how I'd probably want
to use it?
- Exported functions should also include detailed information the caller of the
function will likely need to know and/or understand:
**WRONG**
```Go
// convert a compact uint32 to big.Int
func CompactToBig(compact uint32) *big.Int {
```
**RIGHT**
```Go
// CompactToBig converts a compact representation of a whole number N to a
// big integer. The representation is similar to IEEE754 floating point
// numbers.
//
// Like IEEE754 floating point, there are three basic components: the sign,
// the exponent, and the mantissa. They are broken out as follows:
//
// * the most significant 8 bits represent the unsigned base 256 exponent
// * bit 23 (the 24th bit) represents the sign bit
// * the least significant 23 bits represent the mantissa
//
// -------------------------------------------------
// | Exponent | Sign | Mantissa |
// -------------------------------------------------
// | 8 bits [31-24] | 1 bit [23] | 23 bits [22-00] |
// -------------------------------------------------
//
// The formula to calculate N is:
// N = (-1^sign) * mantissa * 256^(exponent-3)
//
// This compact form is only used in bitcoin to encode unsigned 256-bit numbers
// which represent difficulty targets, thus there really is not a need for a
// sign bit, but it is implemented here to stay consistent with bitcoind.
func CompactToBig(compact uint32) *big.Int {
```
- Comments in the body of the code are highly encouraged, but they should
explain the intention of the code as opposed to just calling out the
obvious
**WRONG**
```Go
// return err if amt is less than 5460
if amt < 5460 {
return err
}
```
**RIGHT**
```Go
// Treat transactions with amounts less than the amount which is considered dust
// as non-standard.
if amt < 5460 {
return err
}
```
**NOTE:** The above should really use a constant as opposed to a magic number,
but it was left as a magic number to show how much of a difference a good
comment can make.
## Model Git Commit Messages
This project prefers to keep a clean commit history with well-formed commit
messages. This section illustrates a model commit message and provides a bit
of background for it. This content was originally created by Tim Pope and made
available on his website, however that website is no longer active, so it is
being provided here.
Here’s a model Git commit message:
```text
Short (50 chars or less) summary of changes
More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. In some contexts, the first line is treated as the
subject of an email and the rest of the text as the body. The blank
line separating the summary from the body is critical (unless you omit
the body entirely); tools like rebase can get confused if you run the
two together.
Write your commit message in the present tense: "Fix bug" and not "Fixed
bug." This convention matches up with commit messages generated by
commands like git merge and git revert.
Further paragraphs come after blank lines.
- Bullet points are okay, too
- Typically a hyphen or asterisk is used for the bullet, preceded by a
single space, with blank lines in between, but conventions vary here
- Use a hanging indent
```
Prefix the summary with the subsystem/package when possible. Many other
projects make use of the code and this makes it easier for them to tell when
something they're using has changed. Have a look at [past
commits](https://github.com/btcsuite/btcd/commits/master) for examples of
commit messages.
Here are some of the reasons why wrapping your commit messages to 72 columns is
a good thing.
- git log doesn’t do any special special wrapping of the commit messages. With
the default pager of less -S, this means your paragraphs flow far off the edge
of the screen, making them difficult to read. On an 80 column terminal, if we
subtract 4 columns for the indent on the left and 4 more for symmetry on the
right, we’re left with 72 columns.
- git format-patch --stdout converts a series of commits to a series of emails,
using the messages for the message body. Good email netiquette dictates we
wrap our plain text emails such that there’s room for a few levels of nested
reply indicators without overflow in an 80 column terminal.
## Code Approval Process
This section describes the code approval process that is used for code
contributions. This is how to get your changes into btcd.
## Code Review
All code which is submitted will need to be reviewed before inclusion into the
master branch. This process is performed by the project maintainers and usually
other committers who are interested in the area you are working in as well.
## Code Review Timeframe
The timeframe for a code review will vary greatly depending on factors such as
the number of other pull requests which need to be reviewed, the size and
complexity of the contribution, how well you followed the guidelines presented
on this page, and how easy it is for the reviewers to digest your commits. For
example, if you make one monolithic commit that makes sweeping changes to things
in multiple subsystems, it will obviously take much longer to review. You will
also likely be asked to split the commit into several smaller, and hence more
manageable, commits.
Keeping the above in mind, most small changes will be reviewed within a few
days, while large or far reaching changes may take weeks. This is a good reason
to stick with the [Share Early, Share Often](#ShareOften) development practice
outlined above.
## What is the review looking for?
The review is mainly ensuring the code follows the [Development Practices](#DevelopmentPractices)
and [Code Contribution Standards](#Standards). However, there are a few other
checks which are generally performed as follows:
- The code is stable and has no stability or security concerns
- The code is properly using existing APIs and generally fits well into the
overall architecture
- The change is not something which is deemed inappropriate by community
consensus
## Rework Code (if needed)
After the code review, the change will be accepted immediately if no issues are
found. If there are any concerns or questions, you will be provided with
feedback along with the next steps needed to get your contribution merged with
master. In certain cases the code reviewer(s) or interested committers may help
you rework the code, but generally you will simply be given feedback for you to
make the necessary changes.
This process will continue until the code is finally accepted.
## Acceptance
Once your code is accepted, it will be integrated with the master branch.
Typically it will be rebased and fast-forward merged to master as we prefer to
keep a clean commit history over a tangled weave of merge commits. However,
regardless of the specific merge method used, the code will be integrated with
the master branch and the pull request will be closed.
Rejoice as you will now be listed as a [contributor](https://github.com/btcsuite/btcd/graphs/contributors)!

btcd is an alternative full node bitcoin implementation written in Go (golang).
This project is currently under active development and is in a Beta state. It
is extremely stable and has been in production use since October 2013.
It properly downloads, validates, and serves the block chain using the exact
rules (including consensus bugs) for block acceptance as Bitcoin Core. We have
taken great care to avoid btcd causing a fork to the block chain. It includes a
full block validation testing framework which contains all of the 'official'
block acceptance tests (and some additional ones) that is run on every pull
request to help ensure it properly follows consensus. Also, it passes all of
the JSON test data in the Bitcoin Core code.
It also properly relays newly mined blocks, maintains a transaction pool, and
relays individual transactions that have not yet made it into a block. It
ensures all individual transactions admitted to the pool follow the rules
required by the block chain and also includes more strict checks which filter
transactions based on miner requirements ("standard" transactions).
One key difference between btcd and Bitcoin Core is that btcd does *NOT* include
wallet functionality and this was a very intentional design decision. See the
blog entry [here](https://web.archive.org/web/20171125143919/https://blog.conformal.com/btcd-not-your-moms-bitcoin-daemon)
for more details. This means you can't actually make or receive payments
directly with btcd. That functionality is provided by the
[btcwallet](https://github.com/btcsuite/btcwallet) and
[Paymetheus](https://github.com/btcsuite/Paymetheus) (Windows-only) projects
which are both under active development.

# Installation
The first step is to install btcd. See one of the following sections for
details on how to install on the supported operating systems.
## Requirements
[Go](http://golang.org) 1.16 or newer.
## GPG Verification Key
All official release tags are signed by Conformal so users can ensure the code
has not been tampered with and is coming from the btcsuite developers. To
verify the signature perform the following:
* Download the Conformal public key:
https://raw.githubusercontent.com/btcsuite/btcd/master/release/GIT-GPG-KEY-conformal.txt
* Import the public key into your GPG keyring:
```bash
gpg --import GIT-GPG-KEY-conformal.txt
```
* Verify the release tag with the following command where `TAG_NAME` is a
placeholder for the specific tag:
```bash
git tag -v TAG_NAME
```
## Windows Installation
* Install the MSI available at: [btcd windows installer](https://github.com/btcsuite/btcd/releases)
* Launch btcd from the Start Menu
## Linux/BSD/MacOSX/POSIX Installation
* Install Go according to the [installation instructions](http://golang.org/doc/install)
* Ensure Go was installed properly and is a supported version:
```bash
go version
go env GOROOT GOPATH
```
NOTE: The `GOROOT` and `GOPATH` above must not be the same path. It is
recommended that `GOPATH` is set to a directory in your home directory such as
`~/goprojects` to avoid write permission issues. It is also recommended to add
`$GOPATH/bin` to your `PATH` at this point.
* Run the following commands to obtain btcd, all dependencies, and install it:
```bash
git clone https://github.com/btcsuite/btcd $GOPATH/src/github.com/btcsuite/btcd
cd $GOPATH/src/github.com/btcsuite/btcd
GO111MODULE=on go install -v . ./cmd/...
```
* btcd (and utilities) will now be installed in ```$GOPATH/bin```. If you did
not already add the bin directory to your system path during Go installation,
we recommend you do so now.
## Gentoo Linux Installation
* [Install Layman](https://gitlab.com/bitcoin/gentoo) and enable the Bitcoin overlay.
* Copy or symlink `/var/lib/layman/bitcoin/Documentation/package.keywords/btcd-live` to `/etc/portage/package.keywords/`
* Install btcd: `$ emerge net-p2p/btcd`
## Startup
Typically btcd will run and start downloading the block chain with no extra
configuration necessary, however, there is an optional method to use a
`bootstrap.dat` file that may speed up the initial block chain download process.
* [Using bootstrap.dat](https://github.com/btcsuite/btcd/blob/master/docs/configuration.md#using-bootstrapdat)

3. Update the CA certificate list: `# update-ca-certificates`
## Set your mining software url to use https
`cgminer -o https://127.0.0.1:8334 -u rpcuser -p rpcpassword`
`cgminer -o https://127.0.0.1:9245 -u rpcuser -p rpcpassword`
Alternatively, you can disable TLS with the `--notls` option for the server.

## Introduction
With Docker you can easily set up *btcd* to run your Bitcoin full node. You can find the official *btcd* Docker images on Docker Hub [btcsuite/btcd](https://hub.docker.com/r/btcsuite/btcd). The Docker source file of this image is located at [Dockerfile](https://github.com/btcsuite/btcd/blob/master/Dockerfile).
This documentation focuses on running Docker container with *docker-compose.yml* files. These files are better to read and you can use them as a template for your own use. For more information about Docker and Docker compose visit the official [Docker documentation](https://docs.docker.com/).
## Docker volumes
**Special diskspace hint**: The following examples are using a Docker managed volume. The volume is named *btcd-data* This will use a lot of disk space, because it contains the full Bitcoin blockchain. Please make yourself familiar with [Docker volumes](https://docs.docker.com/storage/volumes/).
The *btcd-data* volume will be reused, if you upgrade your *docker-compose.yml* file. Keep in mind, that it is not automatically removed by Docker, if you delete the btcd container. If you don't need the volume anymore, please delete it manually with the command:
```bash
docker volume ls
docker volume rm btcd-data
```
For binding a local folder to your *btcd* container please read the [Docker documentation](https://docs.docker.com/). The preferred way is to use a Docker managed volume.
## Known error messages when starting the btcd container
We pass all needed arguments to *btcd* as command line parameters in our *docker-compose.yml* file. It doesn't make sense to create a *btcd.conf* file. This would make things too complicated. Anyhow *btcd* will complain with following log messages when starting. These messages can be ignored:
```bash
Error creating a default config file: open /sample-btcd.conf: no such file or directory
...
[WRN] BTCD: open /root/.btcd/btcd.conf: no such file or directory
```
## Examples
### Preamble
All following examples uses some defaults:
- container_name: btcd
Name of the docker container that is be shown by e.g. ```docker ps -a```
- hostname: btcd **(very important to set a fixed name before first start)**
The internal hostname in the docker container. By default, docker is recreating the hostname every time you change the *docker-compose.yml* file. The default hostnames look like *ef00548d4fa5*. This is a problem when using the *btcd* RPC port. The RPC port is using a certificate to validate the hostname. If the hostname changes you need to recreate the certificate. To avoid this, you should set a fixed hostname before the first start. This ensures, that the docker volume is created with a certificate with this hostname.
- restart: unless-stopped
Starts the *btcd* container when Docker starts, except that when the container is stopped (manually or otherwise), it is not restarted even after Docker restarts.
To use the following examples create an empty directory. In this directory create a file named *docker-compose.yml*, copy and paste the example into the *docker-compose.yml* file and run it.
```bash
mkdir ~/btcd-docker
cd ~/btcd-docker
touch docker-compose.yaml
nano docker-compose.yaml (use your favourite editor to edit the compose file)
docker-compose up (creates and starts a new btcd container)
```
With the following commands you can control *docker-compose*:
```docker-compose up -d``` (creates and starts the container in background)
```docker-compose down``` (stops and delete the container. **The docker volume btcd-data will not be deleted**)
```docker-compose stop``` (stops the container)
```docker-compose start``` (starts the container)
```docker ps -a``` (list all running and stopped container)
```docker volume ls``` (lists all docker volumes)
```docker logs btcd``` (shows the log )
```docker-compose help``` (brings up some helpful information)
### Full node without RPC port
Let's start with an easy example. If you just want to create a full node without the need of using the RPC port, you can use the following example. This example will launch *btcd* and exposes only the default p2p port 8333 to the outside world:
```yaml
version: "2"
services:
btcd:
container_name: btcd
hostname: btcd
image: btcsuite/btcd:latest
restart: unless-stopped
volumes:
- btcd-data:/root/.btcd
ports:
- 8333:8333
volumes:
btcd-data:
```
### Full node with RPC port
To use the RPC port of *btcd* you need to specify a *username* and a very strong *password*. If you want to connect to the RPC port from the internet, you need to expose port 8334(RPC) as well.
```yaml
version: "2"
services:
btcd:
container_name: btcd
hostname: btcd
image: btcsuite/btcd:latest
restart: unless-stopped
volumes:
- btcd-data:/root/.btcd
ports:
- 8333:8333
- 8334:8334
command: [
"--rpcuser=[CHOOSE_A_USERNAME]",
"--rpcpass=[CREATE_A_VERY_HARD_PASSWORD]"
]
volumes:
btcd-data:
```
### Full node with RPC port running on TESTNET
To run a node on testnet, you need to provide the *--testnet* argument. The ports for testnet are 18333 (p2p) and 18334 (RPC):
```yaml
version: "2"
services:
btcd:
container_name: btcd
hostname: btcd
image: btcsuite/btcd:latest
restart: unless-stopped
volumes:
- btcd-data:/root/.btcd
ports:
- 18333:18333
- 18334:18334
command: [
"--testnet",
"--rpcuser=[CHOOSE_A_USERNAME]",
"--rpcpass=[CREATE_A_VERY_HARD_PASSWORD]"
]
volumes:
btcd-data:

# `btcd`'s Reproducible Build System
This package contains the build script that the `btcd` project uses in order to
build binaries for each new release. As of `go1.13`, with some new build flags,
binaries are now reproducible, allowing developers to build the binary on
distinct machines, and end up with a byte-for-byte identical binary.
Every release should note which Go version was used to build the release, so
that version should be used for verifying the release.
## Building a New Release
### Tagging and pushing a new tag (for maintainers)
Before running release scripts, a few things need to happen in order to finally
create a release and make sure there are no mistakes in the release process.
First, make sure that before the tagged commit there are modifications to the
[CHANGES](../CHANGES) file committed.
The CHANGES file should be a changelog that roughly mirrors the release notes.
Generally, the PRs that have been merged since the last release have been
listed in the CHANGES file and categorized.
For example, these changes have had the following format in the past:
```
Changes in X.YY.Z (Month Day Year):
- Protocol and Network-related changes:
- PR Title One (#PRNUM)
- PR Title Two (#PRNUMTWO)
...
- RPC changes:
- Crypto changes:
...
- Contributors (alphabetical order):
- Contributor A
- Contributor B
- Contributor C
...
```
If the previous tag is, for example, `vA.B.C`, then you can get the list of
contributors (from `vA.B.C` until the current `HEAD`) using the following command:
```bash
git log vA.B.C..HEAD --pretty="%an" | sort | uniq
```
After committing changes to the CHANGES file, the tagged release commit
should be created.
The tagged commit should be a commit that bumps version numbers in `version.go`
and `cmd/btcctl/version.go`.
For example (taken from [f3ec130](https://github.com/btcsuite/btcd/commit/f3ec13030e4e828869954472cbc51ac36bee5c1d)):
```diff

const (

// appPreRelease MUST only contain characters from semanticAlphabet
// per the semantic versioning spec.
```
Next, this commit should be signed by the maintainer using `git commit -S`.
The commit should be tagged and signed with `git tag <TAG> -s`, and should be
pushed using `git push origin TAG`.
### Building a release on macOS/Linux/Windows (WSL)
No prior set up is needed on Linux or macOS is required in order to build the
release binaries. However, on Windows, the only way to build the release
binaries at the moment is by using the Windows Subsystem Linux. One can build
the release binaries following these steps:
1. `git clone https://github.com/btcsuite/btcd.git`
2. `cd btcd`
3. `./release/release.sh <TAG> # <TAG> is the name of the next release/tag`
This will then create a directory of the form `btcd-<TAG>` containing archives
of the release binaries for each supported operating system and architecture,
and a manifest file containing the hash of each archive.
### Pushing a release (for maintainers)
Now that the directory `btcd-<TAG>` is created, the manifest file needs to be
signed by a maintainer and the release files need to be published to GitHub.
Sign the `manifest-<TAG>.txt` file like so:
```sh
gpg --sign --detach-sig manifest-<TAG>.txt
```
This will create a file named `manifest-<TAG>.txt.sig`, which will must
be included in the release files later.
#### Note before publishing
Before publishing, go through the reproducible build process that is outlined
in this document with the files created from `release/release.sh`. This includes
verifying commit and tag signatures using `git verify-commit` and git `verify-tag`
respectively.
Now that we've double-checked everything and have all of the necessary files,
it's time to publish release files on GitHub.
Follow [this documentation](https://docs.github.com/en/github/administering-a-repository/managing-releases-in-a-repository)
to create a release using the GitHub UI, and make sure to write release notes
which roughly follow the format of [previous release notes](https://github.com/btcsuite/btcd/releases/tag/v0.20.1-beta).
This is different from the [CHANGES](../CHANGES) file, which should be before the
tagged commit in the git history.
Much of the information in the release notes will be the same as the CHANGES
file.
It's important to include the Go version used to produce the release files in
the release notes, so users know the correct version of Go to use to reproduce
and verify the build.
When following the GitHub documentation, include every file in the `btcd-<TAG>`
directory.
At this point, a signed commit and tag on that commit should be pushed to the main
branch. The directory created from running `release/release.sh` should be included
as release files in the GitHub release UI, and the `manifest-<TAG>.txt` file
signature, called `manifest-<TAG>.txt.sig`, should also be included.
A release notes document should be created and written in the GitHub release UI.
Once all of this is done, feel free to click `Publish Release`!
## Verifying a Release
With `go1.13`, it's now possible for third parties to verify release binaries.
Before this version of `go`, one had to trust the release manager(s) to build the
proper binary. With this new system, third parties can now _independently_ run
the release process, and verify that all the hashes of the release binaries
match exactly that of the release binaries produced by said third parties.
To verify a release, one must obtain the following tools (many of these come
installed by default in most Unix systems): `gpg`/`gpg2`, `shashum`, and
`tar`/`unzip`.
Once done, verifiers can proceed with the following steps:
1. Acquire the archive containing the release binaries for one's specific
operating system and architecture, and the manifest file along with its
signature.
2. Verify the signature of the manifest file with `gpg --verify
manifest-<TAG>.txt.sig`. This will require obtaining the PGP keys which
signed the manifest file, which are included in the release notes.
3. Recompute the `SHA256` hash of the archive with `shasum -a 256 <filename>`,
locate the corresponding one in the manifest file, and ensure they match
__exactly__.
At this point, verifiers can use the release binaries acquired if they trust
the integrity of the release manager(s). Otherwise, one can proceed with the
guide to verify the release binaries were built properly by obtaining `shasum`
and `go` (matching the same version used in the release):
4. Extract the release binaries contained within the archive, compute their
hashes as done above, and note them down.
5. Ensure `go` is installed, matching the same version as noted in the release
notes.
6. Obtain a copy of `btcd`'s source code with `git clone
https://github.com/btcsuite/btcd` and checkout the source code of the
release with `git checkout <TAG>`.
7. Proceed to verify the tag with `git verify-tag <TAG>` and compile the
binaries from source for the intended operating system and architecture with
`BTCDBUILDSYS=OS-ARCH ./release/release.sh <TAG>`.
8. Extract the archive found in the `btcd-<TAG>` directory created by the
release script and recompute the `SHA256` hash of the release binaries (btcd
and btcctl) with `shasum -a 256 <filename>`. These should match __exactly__
as the ones noted above.

Package txscript implements the bitcoin transaction script language. There is
a comprehensive test suite.
This package has intentionally been designed so it can be used as a standalone
package for any projects needing to use or validate bitcoin transaction scripts.
This package has been augmented to include support for LBRY's custom claim operations.
See https://lbry.tech/spec
## Bitcoin Scripts
Bitcoin provides a stack-based, FORTH-like language for the scripts in
the bitcoin transactions. This language is not turing complete
although it is still fairly powerful. A description of the language
can be found at https://en.bitcoin.it/wiki/Script
## Installation and Updating
```bash
$ go get -u github.com/btcsuite/btcd/txscript
```
## Examples
* [Standard Pay-to-pubkey-hash Script](https://pkg.go.dev/github.com/btcsuite/btcd/txscript#example-PayToAddrScript)
Demonstrates creating a script which pays to a bitcoin address. It also
prints the created script hex and uses the DisasmString function to display
the disassembled script.
* [Extracting Details from Standard Scripts](https://pkg.go.dev/github.com/btcsuite/btcd/txscript#example-ExtractPkScriptAddrs)
Demonstrates extracting information from a standard public key script.
* [Manually Signing a Transaction Output](https://pkg.go.dev/github.com/btcsuite/btcd/txscript#example-SignTxOutput)
Demonstrates manually creating and signing a redeem transaction.
* [Counting Opcodes in Scripts](http://godoc.org/github.com/decred/dcrd/txscript#example-ScriptTokenizer)
Demonstrates creating a script tokenizer instance and using it to count the
number of opcodes a script contains.
## GPG Verification Key
All official release tags are signed by Conformal so users can ensure the code
has not been tampered with and is coming from the btcsuite developers. To
verify the signature perform the following:
- Download the public key from the Conformal website at
https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
- Import the public key into your GPG keyring:
```bash
gpg --import GIT-GPG-KEY-conformal.txt

protocol level.
